Mark Hughes was able to make a winning start to life as Southampton boss as they beat Wigan 2-0.
Despite being second best to their League One hosts in the opening half, Saints grabbed the decisive opening goal after the break.
Pierre-Emile Hojbjerg headed it in, while Manolo Gabbiadini had a penalty brilliantly saved, before Cedric added a late clincher.
The Saints advance to the semi-finals of the FA Cup for the first time in 15 years.
